An important object of my invention is to provide a liquid circulating heater, which utilizes the circulating liquid used for cooling the engine of a vehicle; the said heater being so disposed as to radiate heat to the interior of a vehicle, simultaneously providing the additional function of acting as an auxiliary cooler for the liquid, before it is passed to the radiator of the vehicle for ultimate cooling prior to its recirculation through the engine.

A further object of my invention is to provide a circulating liquid heater of the aforementioned character, which is equipped with hot air blower means for circulating the hot air forcefully within the interior confines of a vehicle.

A further object of my invention is to provide a circulating liquid heater of the aforementioned character provided with a central opening furnishing a housing for prime mover means connected to a blower fan.

A still further object of my invention is to provide means for retaining frictionally and firmly th said prime mover means in assembly within the central core of the circulating water heater, at the same time holding or gripping the said prime mover in line or circumferential contactual relationship so as to prevent the said prime mover from becoming unduly heated and thus maintain the same cool.

Other objects and advantages of my invention will become clarified as the description is read, and will elucidate th improvements indicated on the accompanying drawings. Like symbols are used to designate like parts in the various figures, in which:

his a fragmentary View of the blowezg or fan means, and is a view taken substantially looking in the direction of arrows 55 on Fig. 3. Referring to Fig. 1, my invention is generally designated l l, and is shown mounted underneath the hood of a vehicle generally designated 5, the

said vehicle being provided with a powereplant or engine 7, and a liquid cooling radiator 8, part of the circulating System for cooling the engine or power-plant ,1.

At the threaded boss, 9, the inlet pipe Iii is nn c d eadin into th inne compartment f the h a er H, t e l qu traversin throu h the quid heate nd subs quently pass n through the connection or piping l2, connected to h p e 3 a th ba e or the radiat r struce s the l quid s c culated both through the radiator 8 and primarily through the heater ,ll, eifectuating a pre-cooling effect, thereby relieving the radiator 8 and preventing its becoming overheated.

The heater structure, per se, is composed of a series of tubular vane elements l4, which are suitably bored in order to receive the U-shaped conduits I5, radially positioned about the center of the heater.

The outer perimetral shell of the heater serves to hold securely in place the U-shaped conduits l5. The core structure 22 is of U-shaped cross-sectional configuration, designated l6, and provided with the lips I! and I8 at the top thereof, in order to receive the cap 39 with mating lips engaging the lips I! and I8 so as to form a sealed arrangement.

Centrally of the element IS a partition 20 is secured, which is of coronal configuration and which subdivides the inner chamber of the element it into compartments l9 and 2|.

Through the cap structure 39, on the one side, the inlet 1 0 is secured to the heater, also passing through the partition, forming the inlet through which the liquid enters at 36.

The outlet 12 is secured to the cap 39 and has its mouth entering the compartment l9, whereas the inlet has its mouth terminating within the compartment 2|. Thus, the liquid, after its circulation through the U-shaped conduits I5, leaves the heater H at the outlet as indicated by the arrow 31.

The core element 22 serves to house the springlike resilient element 23, having a series of promontories 24 and 25, so as to engage the outer surface of the motor 26 in line contactual relationship so as not to heat up the said motor and permit the same to remain cool for its efficient operation.

The motor 26 is frictionally held by the resilient element 23, which, at the same time, prevents it from becoming overheated, by the heater. The motor or prime mover 26 has an extension shaft 32 on which is mounted the bushing 33 of the spider 34 to which are secured by riveting, or any other fastening means, the blower or fan blades 35.

The motor is connected to a source of supply 30, the battery of a vehicle, one terminal thereof 21 being grounded at 3|, the other terminal 28 being connected to the battery or source of electrical power 30, a switch 29 being interposed for optional operation of the motor 26 and the incidental blower fan 35.

When the blower is in operation, after closing the switch 29, the hot water generated or heated by the operation of the engine, passes through the heater and forces heat waves 38, as indicated by the arrows, to be circulated through and within the interior confines of the vehicle, generally designated 6.

The advantages of this heater structure, over the patent hereinabove mentioned and designated, are that the forced blower feed is utilized to more quickly circulate the heated air currents passing through the heater, at the same time more effectively relieving the cooling load of the radiator 8, simultaneously preventing overheating, at the same time providing means for retaining the motor 26 without overheating the same; the entire unit being quite compact and not occupying valuable space within the interior confines of the vehicle for accommodating passengers.

An important feature of the invention is the annular element l6, which provides the connections for the inlet and the outlet, separating the same into two compartments, and at the same time, providing a cored opening for a prime mover to be compactly retained therein.

Another feature resides in the element 23, for frictionally retaining the prime mover and at the same time providing a forced feed blower means for the heated air currents passing through the openings in the water circulating heater, preventing the prime mover from becoming overheated, and also permitting a more eflective distribution of the heated air currents, quickly and rapidly, within the interior confines of an automobile or a passenger vehicle.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

Having thus disclosed and revealed my invention, what I claim as new and desire to secure by Letters Patent, is:

A blower radiating liquid circulating heater, comprising in combination liquid circulating radiator means provided with a central core structure, corrugated and resilient heat insulating means secured within the said central core structure, prime mover means retained frictionally within the confines of the said corrugated and resilient heat insulating means, and blower fan means mounted below the said prime mover to dissipate the heated air currents from the said circulating heater.
